- Calvin Klein CK2 - Gender free is such a big thing at the moment with the likes of clothing and models but what about perfumes? Calvin Klein has brought out its very first "gender free" fragrance. The ad campaign used the elements especially earth and water in a playful way. The colours are vibrant and the use of male and female models to promote the scent. The smell of it is fresh and I can see it being used for both genders!
